Concrete mixing plant works in the face of slope or slope treatment

Concrete is now encountered in the construction of ramps, ramps more and more common. But the slope of the slope of the concrete pouring is relatively more difficult, for different pouring site has a different response program. Whether it is a large area of ​​inclined roof or a small area of ​​inclined roof as long as the method properly, pouring is not a problem.
With the slope of the independent base slope, pouring concrete, most should not vibrate dense. Playing the best independent slope of the support template, in the stencil vibration of concrete, is conducive to forming effect and relatively dense. If there is no branch, then the basic slope is "rice candy." When using the sub-pouring method, each section get a closed stencil, if the slump is small, you can pour a molding, but the vibration is not easy, not vibrating will affect the slope of the compactness, strength and life.
For large-scale inclined roof, it is recommended to use double-sided sealing mold construction technology. Surface layer template spacing to set the pouring groove (pouring groove of the surface layer) template is not sealed, in order to facilitate the concrete cutting, vibration and inspection, while pouring side of the wall sealing trough surface template. The pouring groove is parallel to the ridge direction. Layered pouring. From the bottom of the pouring up, pouring the lower part of each pouring tiles after pouring, sealed here, pouring the trough template, and then through the above a pouring groove for this section of the pouring. Using artificial vibrations and vibrating rods vibrating combination. The vibrating rod is inserted into the concrete lower layer from the pouring groove to vibrate. Manually use steel pipe or hammer to beat the template to ensure that the concrete inside the template is dense. Concrete pouring finished 24 hours to remove the surface layer template, for conservation.
For a small area of ​​inclined roof, do not have to use double-sided closure of the template construction process, leaving only the underlying template. Using concrete with smaller slump to carry out concrete pouring. Side of the placement of workers to receive light, the concrete before the final condensate at least 3 times. Using artificial vibrating (steel plug), light vibration vibrator.
